Opting out of cookies
There are a number of options available so that you do not have to store any cookies at all. You can either set your browser so that it will not accept and store any cookie, or if you have a little more time and knowledge you are able to allow only certain ‘trusted’ sites to store cookies on your computer. These sites may include us (of course!), or the site where you carry out your online banking, or possibly your favourite news service.
It’s worth bearing in mind that if you decide to delete all of your cookies, then you will likely have to re-enter all of your usernames and passwords on all of the sites that you visit, which you previously didn’t even have to think about. As we mentioned before, cookies can be a real asset to your web surfing experience.
The Information Commissioner’s Office provides some advice about cookies and their use, but it also provides a link to ‘About cookies’ ( www.aboutcookies.org ) which is run by the law firm Pinsent Masons. This website provides even more information about cookies if you feel that this page and the ICO is not enough information for you, but it also details how you might delete any cookies that you find, and it also shows you how to allow those trusted sites to store their cookies on your computer.

Adobe uses a particular type of cookie called a ‘Local Shared Object’, which is typically collected if you watch a video for example that uses the Adobe Flash media player, i.e. an embedded YouTube video on a page that is being played via Flash. Please note that these types of cookie will not be found on iPads, which do not support Flash.
Have a look at Adobe's website if you want to control Flash cookies on your computer. If you’ve got a Firefox browser you can also get an add-on to detect and delete Flash cookies.
